No
The device description and performance studies indicate a standard immunochromatographic assay with visual interpretation of colored lines, with no mention of AI or ML.
No.
The device is a diagnostic test intended to measure FSH levels for fertility screening, not to treat or alleviate a medical condition.
Yes
This device measures FSH levels in urine and provides an indication of diminished ovarian reserve, which is a condition related to fertility, thereby aiding in the assessment of a health condition.
No
The device is described as a rapid, immunochromatographic assay, which is a physical test strip that measures FSH in urine. It involves observing colored lines, indicating it is a hardware-based test.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for "measuring follicle-stimulating hormone (FSH) in urine." This involves testing a biological sample (urine) outside of the body to gain information about a person's health status (fertility).
- Device Description: The description details a "rapid, immunochromatographic assay for the measurement of follicle-stimulating hormone (FSH) in human urine." This is a common type of in vitro diagnostic test.
- Performance Studies: The performance studies compare the device's results to established laboratory methods and FDA-cleared assays, which are typical for validating IVD performance.
- Predicate Devices: The listed predicate devices are also IVDs (fertility and menopause tests that measure hormones in biological samples).
The core function of the device is to analyze a biological sample (urine) in vitro (outside the body) to provide diagnostic information (related to fertility). This aligns perfectly with the definition of an In Vitro Diagnostic device.

Device Description
The QuantRx Female Fertility Test is a rapid, immunochromatographic assay for the measurement of follicle-stimulating hormone (FSH) in human urine. The test is performed on day 3 of the menstrual cycle by urinating directly on the absorbent tip or by dipping it in a cup of urine, and observing for the formation of colored lines after 10 minutes. A test line of color intensity greater than or equal to the reference line indicates an FSH level of at least 10 mIU/mL is indicative of diminished ovarian reserve, which corresponds to reduced fertility. A test line intensity of less than the reference line is indicative of normal ovarian reserve.
The QuantRx Female Fertility Test is a two-site, lateral-flow immunoassay for the measurement of follicle-stimulating hormone (FSH) in human female urine. The test employs mouse monoclonal anti-FSH antibody bound to a colloidal gold conjugate as the labeled antibody. As the urine migrates along the sample tip into the absorbent pad, FSH in the urine binds to the labeled antibody forming an antigen-antibody complex. This resulting complex continues to migrate along the test it binds to the anti-FSH capture antibody on the nitrocellulose membrane producing a colored line in the Test (T) section. The intensity of the colored line in the test section at a 10 minute read time is compared with the intensity of the Reference line which is calibrated at 10 mIU/mL of FSH. When the FSH concentration in the urine is less than 10 mIU/mL, the color intensity of the test line is lighter than the reference line. An FSH concentration of less than 10 mIU/mL on the third day of menses is usually indicative of normal ovarian reserve. When the FSH concentration in the urine is equal to or greater than 10 mIU/mL, the color intensity of the test line is equal to or darker than the reference line. An elevated FSH result (equal to or greater than 10 mIU/mL on the third day of menses) is generally indicative of a diminished ovarian reserve.
At the end of the nitrocellulose membrane is a Control section which produces a visible line if the test has been performed properly. The Control line is generated by an antigen/antibody reaction different from the FSH aspect. This Control line should always appear, regardless of the presence or absence of detectable FSH in the urine sample. The absence of a line in the Control section is considered an "invalid" result since it indicates the test did not perform properly due to procedural error or insufficient specimen.

Description of the training set, sample size, data source, and annotation protocol
An over-the-counter study consisting of two-hundred nine (209) females was conducted comparing the performance of the QuantRx Female Fertility Test to a published, validated, quantitative, chemiluminescent method for urine follicle-stimulating hormone (FSH).
In a supplemental consumer study, a total of forty-eight (48) females performed the QuantRx Female Fertility Test using urine specimens where forty (40) of those specimens were derived from consumers who also provided paired serum specimens for comparison with an FDA cleared serum FSH assay (DPC IRMA FSH; K893976).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
An over-the-counter study consisting of two-hundred nine (209) females was conducted comparing the performance of the QuantRx Female Fertility Test to a published, validated, quantitative, chemiluminescent method for urine follicle-stimulating hormone (FSH). In addition to the consumer study, a professional study comparing the performance of the QuantRx Female Fertility Test to this laboratory methodology was conducted using the same combination of freshly-collected urine specimens and blinded control specimens as the consumer study.
In a supplemental consumer study, a total of forty-eight (48) females performed the QuantRx Female Fertility Test using urine specimens where forty (40) of those specimens were derived from consumers who also provided paired serum specimens for comparison with an FDA cleared serum FSH assay (DPC IRMA FSH; K893976). A professional study comparing the performance of the QuantRx Female Fertility Test to the serum FSH results using the same paired urine specimens was also conducted. The concordance for both the professional and layperson users between the laboratory urine method, the FDA cleared serum method and the QuantRx Female Fertility Test demonstrated that the QuantRx Female Fertility Test is safe and effective for its stated intended use.
